Soil in Mora County
Across Mora County, the ground is predominantly Mollisols, where Partri, Apache, and Capulin are the most extensive named soil series. The soil is generally well drained with a loam surface. Topsoil pH runs about 7.0–7.5, neutral. Rainfall drains through hydrologic group D soils.

Is it too late to plant in Mora County?
For most of the year, no — what changes is which crops still fit the days remaining. Cool-season crops can go in from around Mar 20; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Apr 17 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 31 — long-season crops need about 90 days of runway, quick greens only 30. Late in the year the fall bench takes over — quick greens, radishes, and garlic that repays you next summer.
Growing Challenges in New Mexico
What an experienced grower plans around here — each one has a move.
Very low rainfall requires irrigation for most crops
High-desert growing starts with the water plan — drip lines, deep mulch, and basins put scarce rain exactly where roots are.
High altitude UV intensity can burn tender transplants
Harden seedlings slowly and shade-cloth their first week out — high-desert sun is stronger than any indoor start prepares them for.
Alkaline soils limit plant selection without amendment
Test first: knowing your actual pH turns 'what won't grow' into a short, workable amendment list.

What the federal record shows across Mora County — and how to grow with it.
We checked the federal record across Mora County — 44 documented sites across 4 of the 9 source types we track.
The most significant on record: 11 mining sites. Historic and active mines that may leach heavy metals like arsenic, lead, and cadmium.
The federal record across Mora County is light. Growing food here starts from a strong position — a quick pass over the map tells you whether any recorded site sits near your land, and if one does, that's information to plant with, not a reason to stop.
Sources: EPA, USGS — 1.8M documented sites tracked nationwide across 9 federal source types.

A note from Gnorman
What an experienced grower watches for around here
In and around Mora County, two things run higher than the national average — Mining (11 sites) and Underground Storage Tanks (29 sites). It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around it.
Mining: Mining sites — both historic and active — can leach heavy metals (arsenic, lead, cadmium, mercury) into soil and water for centuries after operations cease.
Underground Storage Tanks: Underground storage tanks are the single most common source of soil contamination near homes and gardens.
Test soil for heavy metals (lead, arsenic, cadmium, mercury) — this is essential near any mining site.
Use raised beds with imported soil — this eliminates the primary soil-contact pathway.

Frequently Asked Questions
What hardiness zone is Mora County, New Mexico?
Mora County sits in USDA hardiness zone 6b, per the USDA Plant Hardiness Zone Map 2023. Zones reflect average annual extreme minimum temperatures from 1991–2020 weather data.
Is it too late to plant in Mora County?
For most of the year, no — what changes is which crops still fit the days remaining. Cool-season crops can go in from around Mar 20; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Apr 17 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 31 — long-season crops need about 90 days of runway, quick greens only 30. Late in the year the fall bench takes over — quick greens, radishes, and garlic that repays you next summer.
When does frost risk typically end in Mora County?
The last hard freeze (28°F) in Mora County typically lands around Apr 17, per NOAA 1991–2020 climate normals — an earlier marker than the light-frost dates many planting charts quote. That marks the hard freeze, not the last light frost — light frosts can still bite for a few more weeks, so tender transplants usually wait another 2–3 weeks.
How long is the growing season in Mora County?
Measured between 28°F hard freezes, Mora County sees about 197 frost-free days — roughly Apr 17 through Oct 31, per NOAA 1991–2020 climate normals. Tender crops get a somewhat shorter practical window, since lighter frosts reach a few weeks past the hard-freeze dates on both ends.
What vegetables grow in Mora County?
Mora County's zone 6b supports a wide range — strong performers include Green Chile, Pecan, Pinon Pine, Prickly Pear, and Apache Plume. What actually takes on any one site comes down to its soil, sun, and drainage, and we score each plant against the real conditions at your address.
Which hardiness zone is Mora County, really?
Officially, Mora County sits in USDA zone 6b (USDA PHZM 2023) — but a zone is a 30-year average of winter's coldest night across an area, and it can't see any one yard. A south-facing slope, a tree line, or a low frost pocket can shift a single site by half a zone either way, which is why neighboring gardeners often quote different numbers. We read the conditions at your exact address — soil, sun, slope, and frost — and score 1,112 plants against what's actually there.
Is the soil safe to grow vegetables in Mora County?
The federal record around Mora County is light — 44 documented sites across the 9 federal source types we checked — and proximity to a documented site is information, not a diagnosis of any one yard. Growing food here starts from a strong position; a soil test before new food beds settles any site-specific question.
Just moved to Mora County — what should I know before planting?
Start with three facts. Mora County sits in USDA zone 6b, which sets what survives winter; the last 28°F hard freeze typically clears around Apr 17, with about 197 frost-free days to work with (NOAA 1991–2020 climate normals); and the local federal record is light — 44 documented sites across the area we checked. From there, matching plants to your actual soil and sun is the fun part.
